Answer:
Step-by-step explanation:
we know that
The exponential function is of the form
where
a is the initial value
b is the base
In this problem we have
a=200 birds
b=100%+4%=104%=104/100=1.04
substitute
Let change of variables
where
b is the amount of birds in the flock
d is the number of days since the 200 birds started

Answer:
t = 11.3 hours
Step-by-step explanation:
The formula d = rt stands for distance = rate x time. The problem gives you the rate, or r = 48.3 m/h, and the distance, or d = 545.79m. To solve for 't', you can plug the values given and divide:
d = rt or 545.79 = 48.3(t)
Divide both sides by 48.3: 545.79/48.3 = 48.3t/48.3
Solve for t: t = 11.3 hours
Answer:
114
Step-by-step explanation:
Plug in the numbers into the equation
2(3*3+2*12*2)
then solve in the parenthesis (PEMDAS)
2(9+48)
2(57)
then multiply by 2
114
Answer:
Step-by-step explanation:
In the diagram below we have
ABCD is a parallelogram. K is the point on diagonal BD, such that
And AK meets BC at E
now in Δ AKD and Δ BKE
∠AKD =∠BKE ( vertically opposite angles are equal)
since BC ║ AD and BD is transversal
∠ADK = ∠KBE ( alternate interior angles are equal )
By angle angle (AA) similarity theorem
Δ ADK and Δ EBK are similar
so we have
( ABCD is parallelogram so AD=BC)
( BC= BE+EC)
( subtracting 1 from both side )
taking reciprocal both side
